I did order a Tru Turn lighten spinner for the DA. But I'm sure it isnt as light as the carbon spinner. I plan on using a 6 volt 2000 mah on the receiver and a 1450 mah on the ignition. I'm going to make some cf rods with some 4-40 inserts with ball links on the servo end and the dubro snap links on the control end. I'm using hitec 645 on the ailerons and ele and a 5985 on the rudder. I guess my main concern is...am I "wasteing" the power of the DA on this bird? Would it have more use in a 84-85inch plane? Would I be better off going with the 160 and keep in light or take the chance of it being heavier than I planned and not be as light on the wing with the Da since the wing area is in the 1100 sq range. I've read alot that 50 cc engines are better for a plane with 1300-1400 squares. Those are the questions that keep going through my head Bubba
